▎ 摘　　要

NOVELTY - Polypropylene composition comprises 100 pts. wt. polypropylene resin, 0.2-0.8 pts. wt. graphene, 0.5-7 pts. wt. compatibilizer, and 0-33 pts. wt. other functional additives. The compatibilizer is glycidyl methacrylate grafted polypropylene. USE - Polypropylene composition for preparating automotive interior units (claimed). ADVANTAGE - The polypropylene composition can ensure better dispersion of graphene and effectively improve the light transmittance of polypropylene materials by reasonably adjusting the amount of graphene and adding a specific compatibilizer glycidyl methacrylate grafted to polypropylene rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the polypropylene composition, which involves mixing polypropylene resin, graphene, compatibilizer and other functional additives, and melt extruding to obtain the composition.
